About us: 

At Axite, we’re redefining how brain health is understood and monitored—at home, in real life, and in real time. Born as a spin-out from Leiden University, we blend cutting-edge neuroscience, digital health innovation, and deep personal empathy to bring clarity to conditions that are often invisible.

We created NeuroJournal, a first-of-its-kind brain monitoring tool that helps uncover the cognitive effects of conditions like epilepsy, Long COVID, post-concussion syndrome, and more. By combining EEG technology, smartphone behavior, and machine learning, NeuroJournal captures subtle changes in brain function—translating everyday experiences into meaningful data.

Our journey began with a shared frustration: too many people were living with symptoms like brain fog, cognitive overload, and fatigue yet getting no answers, no diagnosis, and often, no validation. We saw an opportunity to change that.

At Axite, our mission is simple but powerful: to make the invisible visible.

We believe that everyone deserves to be seen, understood, and supported in their brain health journey.

We're a dynamic and diverse team, united by a commitment to human-centered healthcare. From patients and clinicians to researchers and caregivers, we work together to deliver insights that drive faster breakthroughs and truly personalized care.
